Abstract

The invention relates to a filtration apparatus for reducing redundant materials of a liquid rocket motor liquid flow test. The filtration apparatus comprises a first pipeline end head, an end cap, afiltering assembly, a shell and a second pipeline end head, wherein one end of the first pipeline end head is connected to the outlet of a system filter, the other end of the first pipeline end head is sealedly connected to the end cover, one end of the second pipeline end head is connected to a product, the other end of the second pipeline end head is sealedly connected to the shell, the filtering assembly is arranged inside the shell, the end cover is connected to the shell through a fastener, the end cover presses the filtering assembly, and the filtering assembly is used for filtering micro redundant materials un-filtered by the system filter. According to the present invention, the filtration apparatus is arranged between the high-pressure high-flow-rate liquid flow test system filterand the product, can perform multiple filtrations on the micro redundant materials un-filtered by the system filter, and can ensure the validity of the test data and the reliability of the product.

Description

technical field

[0001] The invention relates to a filtering device for reducing the redundant objects in the liquid flow test of a liquid rocket engine, and belongs to the field of prevention and control of the redundant objects in the liquid flow test of the parts and components of the liquid rocket engine. Background technique

[0002] Liquid rocket engine technology is an experimental technology. Every component on the engine must pass strict ground test assessments to fully verify its working performance and reliability, and ensure that it is safe before participating in flight tests or launch missions. Therefore, testing is the basis for the development and batch production of liquid rocket engines, and the liquid flow test bench is just one of the test methods to verify whether the engine components meet the requirements.

[0003] 1. Introduction of the liquid flow test bench: The liquid rocket engine liquid flow test bench mainly tests the relationship between the thr...
